omake does not compile with 4.04.0 (but omake-git does).

omake has a new mantainer, Gerd Stolpmann, and a new webpage:

http://projects.camlcity.org/projects/omake.html

I couldn't compile omake with ocaml 4.02.1-1, so I made change in disable-warnings.patch:

I couldn't compile omake with ocaml 4.02.1.

So I made change in disable-warnings.patch.

Hello, picked up the package.
It can be created and used, so I hope it's ok as it is.
Please drop me a note, if it needs to be enhanced.

hmhh, the omake-hompage is weird: 0.99 is older than 0.9.8.6 ?!

I made change in disable-warnings.patch.
Please use this if you use ocaml 4.01.0.

Now I can't compile omake with ocaml 4.01.0.

I think, it is because (or) and (&) are obsolute now and that warnings abort the build.
"disable-warnings.patch" doesn't work for this warning.

(Consolidating two comments.) To compile against ocaml 3.12, you have to specify that warnings 9 and 29 shouldn't abort the build. Applying this patch to the PKGBUILD does the trick:
